Sounds like a great addition to the growing list of interesting BRP books. I don't keep very up to date with the hobby as such, but it seems there's a definite trend of back to basics roleplaying, humourous or not. All those 1st Ed (A)D&D games, even a The Fantasy Trip look-alike.
(Some people must have gotten fed up with angsty vampires. Now
that is ripe for a spoof game.)
I know SJG are doing something similar with their GURPS: Dungeon Fantasy series.
Something like this for BRP would be great fun.
